SPECIFICATION forming part of Letters Patent No. 365,291, dated June 21, 1887.

Application filed Novtmbcr 18,.181' 6. Serial No. 210,581. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES D. AUSTIN, of the city of Amsterdam, county of Montgomery, State of New York, have invented new and useful Improvements in Thread-Roll Pins for Bobbin-Winders, of which the following is a specification.

My invention relates to that class of attachments which are used in connection with bobbin-winders and around which the thread or yarn coming from the cop passes before being wound onto the bobbin.

This class of devices have heretofore been made of metal, and they generally consist of a plate having an upper surface that is rounded coincidently with the bar or support on which the device is placed, and a pin upwardly projected from the plate, around which pin and over which plate the yarn or thread coming from the cop passes before being wound onto the bobbin. When this plate and pin are so made of metal, the passing yarn or thread, by its friction against the pin, aided by the grit or sand in the yarn, wears away the pin at the bottom, so as to form a rut or groove therein. This groove proves a source of trouble, owing to the fact that any bunch or knot on the yarn causes the latter to be caught in the groove, when the yarn is often broken thereby. To remedy this difliculty is the object of my in vention, and this I accomplish by making the pin and plate of glass and so constructing these connected parts that they can be attached to a bar for support.

Accompanying this specification, to form a part of it, there are two plates of drawings containing four figures illustrating my invention, with the same designation of parts by letters of reference used in all of them.

Of these illustrations, Figure 1 is a front view of a portion of a bobbin-winder containing a cop, cop-holder, bobbin, conepresser, and with my improved thread-roll pin ap plied thereto. Fig. 2 showsa side elevation of a part of a supporting-bar having one of my improved thread-roll pins inserted therein, with the parts of this figure shown in larger proportion than at Fig. 1. Fig. 3 shows a perspective of my improved threadroll pin as detached from its support.

Fig. at shows a 1 cut, is-

cross vertical section taken on the line 90 x of Fig. 3.

The several parts of the mechanism thus illustrated, as well as those containing my invention, are designated by letters of reference, and the function of the parts is described as follows:

The letter F designates the frame supporting the mechanism; 13, the bobbin; N, the conepresser; G, the cop, and G the cop holder, all of which are of the usual and ordinary construction.

The letter H designates the thread-roll pin, which is made of the plate p and pin 1), and of glass. The plate 1) has produced in its ends 6;, the grooves or passage ways I, which are formed therein for the reception of screws t, to connect it with the support S.

The letters R indicate a recess formed in the bar or support S for the reception of the plate 1)". The letter 9 designates a bevel formed on the pin 1) at its base and around the same, by which the surface of the pin thercat slants away from the straight sides of the latter to connect with the base-plate. This incline or bevel upon the base of the pin forms, in connection with the exterior of the base-plate, a better surface for the movement of the passing yarn Y than if it run in the angle formed between the sides of the pin and top of the base-plate with the bevel omitted.

These thread-roll pins and their haseplate by my improvement are made of glass that is molded or pressed into form as a single piece. 8 5 They are easily attached by means of screws inserted in the end grooves or passages in the baseplate, and made fast by being entered into the wooden bar or support in which the base-plate is secured; and, if desired, washers 0 of lead or other yielding material may be inserted between the screw-heads and the glass. \Vhen so made and attached, the yarn passing to the bobbin runs over them without enough wearing friction to be discernible, and no fur- 5 rows or grooves are made therein, as is the case when these devices are made of metal.

Having thus described my invention, what I claim, and desire to secure by Letters Patr A thread-roll pinfor bobbinwinders, made of glass; having the pin 19 and base'plate 10 with the intervening bevel, g, and adapted to be attached to a support by the means and in 5 the manner substantially asand for the purposes set forth. 7

' Signed at Amsterdam, New York, this 9th day of June, 1886, and in the presence of the two witnesses whose names are hereto written.
